Paul Walker Death: Cause of Accident May Take 90 Days to Confirm

Detectives are investigating the scene of Paul Walker's death -- and it may take several months to determine the cause of the Nov. 30 accident that killed the Fast and Furious actor and friend Roger Rodas.

The exact cause as to why the 2005 Porsche Carrera GT that Rodas was driving careened out of control, may take another 90 days to confirm, according to The Hollywood Reporter. Detective Jeff Maag told the mag, "We’re creating a factual diagram -- mapping the scene. To the extent that we can, we need to rule out mechanical failure. But the car is a mess." Detective Maag also told THR that the vehicle was moving at least 45 miles per hour before the accident took place.

As previously reported, the sports car lurched off the road and smashed into three trees and a street lamp post, causing the car to burst into flames. Both men were pronounced dead at the scene. The L.A. County Coroner's Office determined on Dec. 4 that Walker, who was 40 at the time of death, had passed away from a combination of "traumatic and thermal injuries." The late actor's financial advisor Rodas died upon impact.
